Ratcatcher: Field Members Cubbing
Ratcatcher is required for the field while cubbing.
Coat - A "hacking" jacket of muted pattern and of a weight to suit the temperature.
Neckwear - Necktie or colored stock for men and women preferred, although turtleneck or ladies' riding blouse with neckband or "choker" is acceptable. White stocks should not be worn with hacking jackets.
Breeches - Rust or beige.
Boots - Traditionally brown, but plain-topped black are acceptable. Jodhpurs and paddock boots are also acceptable. Rubber boots, when properly polished, are quite acceptable. All boots, however, require thoughtful maintenance; a rider with clean, glistening boots most often also has clean tack, a well-schooled horse and is a good neighbor in the field.
Waistcoat (vest) - Tattersall. Optional in hot weather.
Headgear -- Caps with ribbons firmly fixed up, bowler or caliente with black cover. Brown is also an acceptable cap color for cubbing or Ratcatcher only.
Gloves - Natural colored leather are preferred. Optional in hot weather. White string are proper on rainy days.
